Description

Technical Field

[0001] This utility model relates to the field of bridge positioning, and more specifically, to a bridge positioning device based on BIM technology. Background Technology

[0002] BIM technology is an engineering data model based on three-dimensional digital technology, integrating various relevant information of a building project. BIM is a digital representation of the physical and functional characteristics of a building project. A complete information model can connect data, processes, and resources at different stages of the building project's life cycle. It is a complete description of the engineering object. BIM is also a digital book method applied to design, construction, and management, which can significantly improve the efficiency and greatly reduce the risks of building projects throughout their entire process. Based on the bridge model data stored in BIM technology, it is convenient to process and prefabricate the bridge bearings as a whole. During the operation of a bridge, the stability and safety of the bridge structure are of paramount importance. However, current bridges lack displacement monitoring and positioning structures. During use, bridges are prone to displacement and other abnormalities due to natural environmental factors or heavy vehicles. However, due to the lack of effective displacement monitoring and positioning structures, it is difficult for managers to accurately and in real time detect whether the bridge has shifted. If even minor displacements are not detected in time, they can easily lead to more serious problems such as crack expansion and increased structural deformation over time, ultimately endangering the safe use of the bridge and posing a huge safety hazard to pedestrians and vehicles. Therefore, a bridge positioning device based on BIM technology is proposed to address the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bridge positioning device based on BIM technology, comprising a support member and a fixing plate. An adjusting member is provided above the support member, and a monitoring plate is provided on one side of the adjusting member. A laser rangefinder and a displacement sensor are respectively fixedly installed on one side of the monitoring plate.

It can also adjust the position of the monitoring components of the monitoring plate, so that the monitoring plate can be accurately aligned with the fixed plate installed on the bridge, which facilitates displacement positioning monitoring.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0017] As attached Figures 1-4 The bridge positioning device based on BIM technology shown includes a support member 1 and a fixing plate 8. An adjusting member 2 is provided above the support member 1, and a monitoring plate 3 is provided on one side of the adjusting member 2. A laser rangefinder 4 and a displacement sensor 5 are fixedly installed on one side of the monitoring plate 3. The displacement sensor 5 converts light signals into electrical signals through the photoelectric effect to measure displacement. For example, when an object blocks or reflects light, the light intensity received by the displacement sensor 5 changes. After processing, the displacement information of the object can be obtained. The laser rangefinder 4 emits a laser beam to measure the distance from the instrument to the target point on the bridge. The displacement and settlement of the bridge are calculated through the measurement data. A support plate 6 is fixedly installed on one side of the support member 1, and a monitoring and positioning host 7 is fixedly installed on one side of the support plate 6. A reflecting prism 9 is fixedly installed on one side of the fixing plate 8, and a displacement sensing plate 10 is fixedly installed on one side of the fixing plate 8.

[0018] As can be seen from the above description, this utility model has the following beneficial effects: by emitting a laser beam to the reflecting prism 9 through the laser rangefinder 4 and measuring the round-trip time, the distance change between the monitoring plate 3 and the fixed plate 8 can be accurately calculated. The monitoring and positioning host 7 is connected to the laser rangefinder 4 and the displacement sensor 5, and receives the data collected by them in real time. In addition, the monitoring and positioning host 7 has a built-in corresponding algorithm and processing program, which analyzes the received distance change data and displacement change data. By calculating, comparing and analyzing these data, it determines whether the bridge has been displaced and the degree and direction of the displacement, and transmits the information to the system monitoring terminal and the mobile terminal through the built-in communication module. Example 2

[0019] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: like Figures 1-4 As shown, in a preferred embodiment, the support member 1 includes a support cover 101. A telescopic plate 102 is slidably connected to the inner wall of the support cover 101. The upper surface of the telescopic plate 102 is connected to the bottom surface of the adjusting member 2. A fixing screw 105 is fixedly connected to the outer surface of the telescopic plate 102. A strip hole 103 is opened on the outer surface of the support cover 101. One end of the fixing screw 105 passes through the strip hole 103 and extends to the outside of the strip hole 103. A fixing nut 104 is threadedly connected to the outer surface of the fixing screw 105. Furthermore, by sliding the telescopic plate 102 inside the support cover 101, and by the fixing screw 105 passing through the strip hole 103 and being threadedly connected to the fixing nut 104, the overall height of the support member 1 can be flexibly adjusted according to the actual installation environment, thereby facilitating the adjustment of the monitoring height.

[0020] like Figures 1-4 As shown, in a preferred embodiment, the adjusting member 2 includes an adjusting plate 201, an adjusting block 202 slidably connected to the inner wall of the adjusting plate 201, one side of the adjusting block 202 being fixedly installed with one side of the monitoring plate 3, a limiting groove 203 being formed in the inner bottom wall of the adjusting plate 201, an adjusting hole 205 being formed on the upper surface of the adjusting plate 201, a locking screw 204 being provided inside the adjusting hole 205, and the locking screw 204 being threadedly matched with the inner wall of the adjusting block 202, two fixing members 11 being fixedly connected to the outer surface of the fixing plate 8, each fixing member 11 having a fixing hole 12 on its outer surface, and a supporting base plate 13 being fixedly connected to the bottom surface of the supporting member 1, the bottom surface of the supporting base plate 13 having a fixing hole 12. Two sets of mounting holes 14 are provided. Furthermore, the position of the monitoring plate 3 can be adjusted by sliding the inner wall of the adjusting plate 201 against the surface of the adjusting block 202, which can adapt to the monitoring needs of different positions. The adjustment hole 205 and the locking screw 204 can limit and fix the movement of the adjusting block 202, ensuring the stability of the adjustment process. The setting of the limiting groove 203 can limit the adjusting block 202, enabling it to slide stably. The support base plate 13 and the two sets of mounting holes 14 can be used to fix the entire device on a stable foundation. The fixing part 11 and the fixing hole 12 can fix the component to one side of the bridge, which is convenient for corresponding monitoring with the monitoring component.

[0021] The working process of this utility model is as follows: In the later use of this BIM-based bridge positioning device, the support component 1 is first installed and fixed above the horizontal plane. Then, the fixing plate 8 is fixed above the bridge, and the monitoring position is adjusted by the adjusting component 2 so that the monitoring component is located on one side of the fixing plate 8. During operation, the laser rangefinder 4 and displacement sensor 5 on the monitoring plate 3 monitor the bridge. The laser rangefinder 4 emits a laser beam towards the reflecting prism 9 on the fixing plate 8. By measuring the round-trip time of the laser, the distance change between the monitoring plate 3 and the fixing plate 8 is accurately calculated. Meanwhile, the displacement sensor 5 senses the position change of the displacement sensing plate 10 in real time, thereby obtaining the displacement data of the bridge structure under the influence of complex factors such as vehicle load and environmental changes. Then, the monitoring data is transmitted to the monitoring and positioning host 7. The monitoring and positioning host 7 analyzes and processes the data and presents the bridge displacement status to the management personnel in a visual manner. This is the working process and working principle of the device.

[0022] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
